This software contain two examples gatest.m and gatest.1.By running the programs as they are in the default folder. The allocation minimum fuel cost and transmission losses can be determined.

% The Example system is taken from the book Power System Analysis by Prof Haadi Sadaat Example 7.8
% the data matrix should have 5 columns of fuel cost coefficients and plant limits.
% 1.a ($/MW^2) 2. b $/MW 3. c ($) 4.lower lomit(MW) 5.Upper limit(MW)
%no of rows denote the no of plants(n)

I can not run this file could u help me more please?

how i implement GA without B coefficient

A homework project of little benefit to anybody with access to GA Toolbox docs. 'Economic dispatch problem' is apparently a scheduling one; there are several submissions on FEX (including some by Yi Cao) addressing it.
